The Lowdown
Alright, listen up. The start of this run is a bit of a mixed bag. We’ve got a consistent pulse of NW groundswell heading our way, but for the first few days the wind is gonna be a real obstacle. Don’t get too excited for Monday. We’re looking at a wait-and-see kind of week before the real quality shows up.
Monday, September 14 kicks things off with a 4ft NW swell at 12 seconds. Those are decent numbers, and the morning is glassy clean with E wind at 3 mph. The problem is the combined energy is only moderate (423). The water is a very unusual 73°, which is much warmer than normal for this time of year. But the afternoon turns onshore, and the quality tanks. The first real standout is over a week away, so be patient.
We have a block of ordinary days from Tuesday through until Thursday the 17th. Winds shift around, but it’s mostly cross or cross-on, and the swell is all over the place – from small 2ft up to 6ft but with poor conditions. Energy peaks Thursday morning at 659 (still moderate), but the cross-onshore wind ruins it.
Friday, September 18 is a little better. The morning is clean with a light cross-offshore wind from the WNW and a 4ft NW swell. The afternoon bumps up to 6ft, but gets a cross-shore chop. Still ordinary.
Now, Saturday, September 19. This is where we get serious. Saturday morning, the wind goes glassy again from the E at 3 mph. The swell jumps to 8ft from the NW with a 13-second period. That’s a solid groundswell. The combined energy rips into strong territory (1756). This is excellent for experienced surfers only. It will be a big, powerful wave. Karramarro is a point break, so this long-period NW swell will wrap in nicely and give you long, lined-up walls. The downside? The point is inconsistent anyway, and it gets crowded often, so expect company.
Sunday, September 20 cleans up again in the morning. Glassy NE wind at 3 mph, with a 5ft NW swell. Energy drops a little (563) but it’s still a very clean, fun-size wave. Good for intermediate surfers too.
Monday, September 21 might be the pick of the whole run. Total flat calm, zero wind. A beautiful 7ft NW swell with a very long 14-second period. The energy reading is huge (1787), very strong. This is a proper groundswell, pushing maximum power. The point will hold it, but it will be big and pushing. Again, only for experts. The crowd factor will be serious, but the surf will be epic.
Tuesday, September 22 is still good. Glassy morning, no wind, 5ft NW swell at 13 seconds. Still powerful, still clean, and a little more manageable than the day before. Energy is still strong (768). Very good morning session.
After that, the swell slowly winds down from the 23rd onwards. We get some clean mornings (like Wednesday 23rd and Saturday 26th) with smaller surf in the 3ft to 5ft range, but nothing to write home about. There’s a small spike in the very long range – Monday, September 28 – with a 6ft NW swell and a clean cross-offshore wind from the W. Energy is moderate (799). It’s worth keeping an eye on, but it’s far out.
Overall, the standout window is the weekend of September 19 and 21. If you are an experienced surfer and don’t mind a crew, that’s your time. For everyone else, aim for Sunday the 20th or Tuesday the 22nd for clean, solid waves.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Karramarro is 3 km (2 miles) from Zarautz. If you plan a holiday in Pais Vasco, look for hotels and other accommodation in Zarautz. Zarautz has rooms for a wide range of budgets as well as car hire and transport links.
